Exploring the Potential of Two Bacterial Consortia to Degrade Cellulosic Biomass for Biotechnological Applications.

This paper outlines two cellulolytic bacterial consortia named SCS and SCB, isolated from soil samples of sugarcane (Saccharum officinarum) crop field, and a sugarcane bagasse deposit in an ethanol mill. Both consortia were able to grow on different carbon sources, such as sugarcane bagasse, corn husk, peanut hulls, and carboxymethylcellulose, releasing up to 11.90 µmol/mL and 15.

Properties of Polyhydroxyalkanoate Granules and Bioemulsifiers from Pseudomonas sp. and Burkholderia sp. Isolates Growing on Glucose.

A Burkholderia and Pseudomonas species designated as AB4 and AS1, respectively, were isolated from soil containing decomposing straw or sugar cane bagasse collected from Brazil. This study sought to evaluate the capacities of culture media, cell-free medium, and crude lysate preparations (containing PHB inclusion bodies) from bacterial cell cultures to stabilize emulsions with several hydrophobic compounds. Four conditions showed good production of bioemulsifiers (E24 ≥ 50 %), headed by substantially cell-free media from bacterial cell cultures in which bacterial isolates from Burkholderia sp.

Chemical and rheological properties of exopolysaccharides produced by four isolates of rhizobia.

The rheological, physicochemical properties, emulsification and stability of exopolysaccharides (EPSs) from four rhizobia isolates (LBMP-C01, LBMP-C02, LBMP-C03 and LBMP-C04) were studied. The EPS yields of isolates under these experimental conditions were in the range of 1.5-6.
